The evaporation and crystallization of a droplet and a thin layer of aqueous solutions of LiBr and LiCl salts on a heated wall with a temperature T_w = 86°C were studied experimentally. Crystallization curves were obtained for a wide range of initial salt concentrations. For the first time it was shown that for different C₀₁ values the crystallization rates J_cr were different; the J_cr curve was nonlinear. With C₀₁ decreasing, the supersaturation at the onset of crystallization increased, because of different induction times with respect to the generation of the first active crystallization center. It is known for relatively large crystals that heat transfer influences the rate of crystallization. Processing of the experimental data with due account of the basic thermophysical parameters shows that supersaturation also affects the crystal growth. The crystallization rate in a thin layer is significantly higher than in a droplet. It was found that description of crystallization in a droplet should take into account strong anisotropy of the crystallization.

液滴和层表面盐溶液的结晶

实验研究了在温度为T _w = 86°C的加热壁上液滴和LiBr和LiCl盐水溶液的薄层的蒸发和结晶。获得了各种初始盐浓度的结晶曲线。首次表明，对于不同的C ₀₁值，结晶速率J _cr是不同的。所述Ĵ _CR曲线是非线性的。带C ₀₁降低时，由于关于第一活性结晶中心的产生的诱导时间不同，所以结晶开始时的过饱和度增加。众所周知，对于较大的晶体，热传递会影响结晶速率。在适当考虑基本热物理参数的情况下处理实验数据表明，过饱和也会影响晶体的生长。薄层中的结晶速率明显高于液滴中的结晶速率。已经发现，在液滴中进行结晶的描述应考虑到结晶的强各向异性。
